Benefits of technology

The invention relates to an agricultural harvesting head that has a frame, conveyors for carrying cut crop material, an upper conveyor, and a diverter roller for directing cut crop material onto the upper conveyor. The upper conveyor has an endless belt that engages and compresses the cut crop material, and a rearmost roller at the rear of the frame. The diverter rollers have a cylindrical body with ribs and protrusions to guide the cut crop material onto the upper conveyor. The technical effects of the invention are improved distribution of cut crop material, reduced clogging, and improved handling of the materials during the harvest process.

Problems solved by technology

None of these have been completely satisfactory.

Embodiment Construction

[0021]FIGS. 1 and 2 show a harvesting head 100. The harvesting head 100 comprises a frame 102 and a rear wall 112. The frame 102 supports the rear wall 112.

[0022]The rear wall 112 has an aperture 114 passing therethrough from the front of the harvesting head 100 through to the rear of the harvesting head 100.

[0023]The harvesting head 100 further comprises a left side conveyor 106, a right side conveyor 110, and the center conveyor 108. The center conveyor 108, the right side conveyor 110, and the center conveyor 108 are all endless belt conveyors. Each conveyor is supported on at least two rollers (not shown) at least one of which is a drive roller that is driven in rotation by a motor. The conveyors convey crop material in the directions indicated by the arrows superimposed on the surfaces of the endless belts.

[0024]The harvesting head 100 further comprises a reciprocating knife 104 that is elongate, and extends across substantially the entire width of the harvesting head 100. The ...

Abstract

An agricultural harvesting head (100) has a frame (102) that extends laterally and is elongate; a left side conveyor (106); a right side conveyor (110); a center conveyor (108, 144); and an upper conveyor (118) of an endless belt type that is disposed to receive, engage and downwardly compress an upper surface of the cut crop material conveyed rearwardly by the center conveyor (108, 144).

Description

FIELD OF THE INVENTION[0001]The invention relates to agricultural harvesting equipment. More particularly, it relates to agricultural harvesting heads. Even more particularly it relates to feed systems for agricultural harvesting heads.BACKGROUND OF THE INVENTION[0002]Harvesting heads of the draper type use endless belt conveyors to move crop material inwardly from the ends of the harvesting head to a central region of the harvesting head, and then rearwardly from a central region, underneath a feed roller, and then through an aperture in the back of the harvesting head and into a feederhouse that extends forward from the agricultural combine on which the agricultural harvesting head is mounted.[0003]The feed roller engages the top surface of the crop mat being fed rearward from the two side conveyors. Several adaptations of been tried over the years, including fingers fixed to the outside surface of the feed roller, fingers that extend and retract into the feed roller based upon it...
